The 24-year old was selected in Alejandro Sabella's initial squad to face Venezuela and Bolivia in World Cup qualifiers beginning on Friday but has since been sent home in order to continue the treatment on the pr0oblem which has kept him sidelined since February 24.

"My knee is better but the squad's physicians would rather have me be safe and stick with the treatments until it's completely healed," he posted on Twitter.

"It's a pity to miss out on the national squad matches but I'll be cheering for Argentina from Manchester, while I finish the recovery."
